They also released an official art with angels. They have wings and all. While this is still possible to tie-in with your theory, but what about Dante explicitly said to be a half-angel? In your theory it is impossible. Using your example, you cannot be a half-Grey Warden - you either is one or not at all.

Also, the demons in DMC are already pretty un-biblical. I bet angels won't be either.
